" UNITED STATES PATENT OFFICE.

To (ZZZ whom it may concern: I

Be it known that I, CHARLES D. ADAMs,-a citizen of the United States, and a resident of Sylvania, in the county of Screven and State of Georgia, have invented a new and Improved Agricultural Implement, of which the following is a full, clear, and exact description.

My invention relates to a machine which is adapted for purposes of general utility, and especially for the purpose of'preparing and While I have called it an agricultural implement, it is to be understood that its utility is not limited to agricultural purposes, as it can be applied in many other occupations, as will be apparent from the descri tion.

The principa objects of the present invention are to provide a machine of the character mentioned with a motor to be driven by electricity, gas, gasolene, or the like, to connect the motor with traction-wheels so as to propel the machine, and to attach various kinds of implements to it in such a manner that they can be readily operated either by the motor or by the forward motion of the machine, at the same time keeping the dimensions of the machine within narrow limits, so that it will be suitable for general use and so that it will not re uire an extraordinarily large expenditure 0 power in operation,

Further objects of the invention will appear in the course of the subjoined description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a horizontal sectional view, on the line 1 1 of Fig. 2, of a machine constructed in accordance with the rinciple of my invention. Fig. 2 is a sectlonal view on the line 2 2 of Fig. 1, and Fig. 3 is a sectional view on the line 3 3 of Fig. 1.

The machine is provided with a frame 10, and on this machine is placed a motor 11 of any desired construction. When this motor is designed to be supplied with gas, gasolene, or oil, a supply-tank 12 is provided and connected with the motor by pipes 13 'and 14. The motor is connected in any suitable manner with a counter-shaft 15, which is provided with a fly-wheel 16 for the usual purpose.

If desired, the shaft may be provided with Specification of Letters Patent.

sired kind of implement or it can be supplied with a clutch-pulley 18 to make the machine of eneral utility when not at Work in the fiel s, as it may be coupled up with any desired kind of machine.

In order to propel the machine, the shaft 15 is provided with a pair of friction-wheels 19 and 20, between which is located a third friction-wheel 21, adapted to'be moved into contact with the face of either of the firstmentioned wheels. This will provide for operating the wheel 21 in either direction and at any desired speed, according to the distance which it may be located from the shaft.

17 for driving any de- The wheel 21 is mounted on a shaft 22, which is longitudinally and laterally movable, and is connected, preferably, by a universal joint 23 with 'a longitudinal sliding shaft 24. This shaft is provided With a pair of collars 25, upon which a lever 25*, pivoted upon the frame, is adapted to operate to reciprocate the shaft.

The shaft 24 has a bearing in a bushing 24" and has a square portion 26, passing through said bushing and through a gear-wheel 27. This gear-wheel is slidably mounted with respect to the shaft, but is held in a stationary osition by a bracket 28 while the shaft sides through it. The gear-wheel meshes with a gear 29 upon a main shaft 30. .At the two ends of the shaft 30 are a pair of extensionshafts 31, each having a clutch member 32,

adapted to engage with a clutch member 33 on the shaft 30. A pair of levers 34 are pivoted upon the frame for operating the clutch members 33, so as to throw either or both of the traction-Wheels 35, which are mounted upon the extension-shafts 31, out of operative connection with the shaft 30. This rovides for steering the machine, as wil be readily understood.

The mechanism so far described is capable of operatin to propel the machine in one direction. I it is desired to reverse the direction of motion of the machine, the shaft 22 is moved laterally, so that the wheel 21 comes I into contact with the other one of the friction-wheels. For this purpose the shaft- 22 is journaled in a movable bearing 36, sliding upon a bar 37 on the frame. The bar 37 is provided with a slot 38 for this purpose and the bearing 36 with a stud 39, passing through the slot. Connected with an extension 40 on the bearing is a link 41, connected with a bell-crank 42' and the latter connected, through a link 43, with alever 44. This lever IIO . ably located in the centra is provided with a catch 45 and a toothed segment 46 for holding it in any desired position. By the mechanism just described the direction of rotation of the shaft 30 and traction wheels can be readily regulated and reversed.

In order to assist in the guiding of the machine, a guide-wheel 47 is rovided, preferl line of the machine and mounted upon a bracket 48, which is capable of turnin upon a pivot 49. For turning this wheel a ever 50 is provided, this lever being connected with an arm 51 upon the bracket 48 by a link 52. The pivot 49 is mounted to oscillate in a cross-bar 53 on the frame, and the bell-crank is adapted to turn the bracket 48 and wheel about the ivot 49. The lever is mounted upon a vertica rod 50*,

which is provided with handles 54 for turn-.

ing it, the rod being pivoted in a socket 55, located on a bracket 56, suspended from the under side of the frame. The lever 50 is connected with a movable frame 58. This frame is provided with a series of perforations 59 in any of which a series of links 60 may be pivoted. Each one of these links is also connected with a vertical rod 61, upon which "a tooth 62 of an agricultural implement is mounted. The rods 61 are pivoted in perforations 63 in a transverse frame 64. The op eration of the rod 53 to turn it about itself as a center will {obviously result in a change in the angle at which the plowshares or harrowteeth are situated with respect to the central line of the vehicle, and the direction in which they point will be parallel at all times to the direction of the wheels 47. Consequently there will be a coaction between these devices, and the steering of the vehicle will be accomplished with either, while it will not interfere with the operation of the cultivator and will not be impeded by them.

The frame 64 consists of two bars separated from each other, and between them is mounted an operating member 65. This member is pivoted upon a shaft 66, which is adapted to be turned by a lever 67, mounted thereon. Upon turning the shaft 66 the operating member will engage one of the members of the frame 64 and raise or lower it.

- It will be seen from this description that the machine, whether constructed in the form shown or in any other form which is included within the scope of my invention, is capable'of necessary adjustments for use with all kinds of cultivating implements and also that it is capable of turning and performing all the manipulations necessary in that class of work. It will alsov be clear how the attachments mentioned above can be supplied, so that the machine'can be used for other than cultivating urposes. Moreover, a spiral screw in the ame bolted on the front of the machine and run by the sprocket-wheel 17 makes an excellent ditching-machine.

This invention can also be applied to a smaller machine for lighter work, so that it can be operated by a person walking.

Having thus described my invention, I claim as new and desireto secure by Letters Patent- 1.
